It comes in all types of flavors Usually a new object is created Copy and information might be lost Change reference type, otherwise throws exception. Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type Casting in java isn't magic, it's you telling the compiler that an object of type a is actually of more specific type b, and thus gaining access to all the methods on b that you wouldn't have had otherwise
You're not performing any kind of magic or conversion when performing casting, you're essentially telling the compiler trust me, i know what i'm doing and i can guarantee you that this. Do you understand the concept of casting Casting is the process of type conversion, which is in java very common because its a statically typed language Is there a possibility that casting a double created via math.round() will still result in a truncated down number no, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal places. In absence of op's clarification, this question could be interpreted in the sense of converting any string to a number, i.e Turning dog into a number (which of course can be done).
The real question is what you want to do when/if the value in the unsigned int it out of the range that can be represented by a signed int If it's in range, just assign it and you're done If it's out of range, that'll give an unspecified result so you'll probably want to reduce it the right range first, or assign it to a larger signed type.
